Here is what I'm facing. I have an RRAS server that we use as our company VPN. While trying to setup L2TP/IPSEC I inadvertently broke something. After removing the roles involved (IIS,ADCA,ect.) I was able to vpn from a laptop in with no problems. However
I cannot vpn from a mobile device, specifically androids. Now this worked before I broke something and it works fine on my iphone so I know its not a Telecom company blocking me. What I thought would be the simplest solution would be to just simply start over.
Uninstall RRAS role and the Network Access and just redo it. However upon removing the role and a reboot all seems well until you go to install the role again. Upon a successful role install you go to routing and remote access and its already configured, with
the settings that I had before which is what I DON'T want. Obviously removing the role doesn't really "remove" everything associated with that role as I have done this several different times just to see if there was some hitch in the process. So how in the
world do you actually remove the configurations associated with a role if removing the role only simply makes it not usable..?
My experience is either reinstall the server or know what configuration changes adding the role does, so you can revert it manually. Either way is extremely troublesome, so having a snapshot to revert to in terms of installation and/or test installation
prior to installation in production is a recommendable.
All in all it comes down to the matter of knowing about your doing and knowing what to expect.
I don't know what the difference is between IOS and Android in terms of VPN, but I can't possibly think they work the same way.
